"The installer (Davis) arrived on time, installed the system in about two hours, and showed me everything I needed to know about the system. The “before”and “after” test results were right in line with my own test measurements, which I took with a portable radon detector. The radon level dropped to a safe level after the system was installed, and that level has been maintained since it was installed in July of 2020, about 10 months ago. Overall, I was extremely pleased with A & R and I highly recommend them for radon mitigation work."

"I highly recommend Apex Radon Solutions. From getting the estimate to getting the work done, everything was just outstanding. Marco and his crew of 3 men showed up early and were all knowledgeable and extremely skilled. I had to install a radon fan and put in piping and electrical. They measured the piping with care and accuracy and did an excellent job with the installation. Iâ m truly impressed with the professionalism and quality of the work. They were also very reasonable with their prices. Thank you Apex for such great work."

"Water Flo is fantastic. From Nick Sunday who did the walk through and estimate to the office staff and the installers, all are professional and friendly. No waiting months for the work to get done. The entire process took less than 2 weeks. Everyone was on time. The installation was neat and clean. The explanation of the equipment was presented so it was easy to understand and the radon system installed has dropped my levels 3 units!"

"John M. was courteous, timely, and professional in his inspection. He was upfront about the issues -- whether they are serious or minor, rare or common, and whether more specialized input is required. His written report was very well done and will serve as a great home guide for us in the future after we move in. Thank you!"

Radon Detection and Reduction questions, answered by experts

The cost for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.

Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don’t hesitate to perform radon testing and install a mitigation system as soon as possible.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

Radon is a cancer-causing radioactive gas that poses serious health risks, infiltrating homes through foundation cracks and unnoticed spaces.
